Electrical supply circuit in an aircraft for electrical equipment, including a de-icing circuit

The invention relates to a power circuit in an aircraft. The power circuit comprises power distribution network (17) and a power generator (27) used for the aircraft. The power distribution network (17) is used for supplying power for power equipment (5b) positioned in an engine of the aircraft or in the environment of the engine. The power generator (27) is integrated in the engine of the aircraft for supplying power for deicing circuit (5a). The power equipment comprises an engine room load (5b) which is connected to DC voltage distribution bus (35), and the power equipment is connected with voltage conversion circuit (34) which is supplied power by the distribution network (17). The deicing circuit (5a) comprises at least one resistance (61) for dissipating electric energy which probably returning from at least a plurality of engine room loads to the DC voltage distribution bus (35).
